Ya since your tank is deeper do you think this fixture would work with mine because its only 8 inches tall lol http://www.bigalsonline.ca/BigAlsCA/...ripwlunarlight

If you can afford it get the dual sattalite it has daylights and actinics. The leds are only 1w moon lights for night. They do not give off the same spectrum light as the actinics. Corals zooplankton needs the bluer color of the spectrum this is some where l\between 420nm and 460nm.

Yeah I know I paid $325 dollors for mine just to tear it apart. But if you skip on your light it will show. Coralife makes the dual fixtures to. I heard(dont know) that they are pretty descent. I lighting can be the biggest expense in a reef setup.

lol brandon thats the retro-fit i already showed you and said ''this would be perfect for your tank'' Dont get any of those light fixtures from big al his prices are way too high.
For the same price you can get this from big alhttp://www.bigalsonline.ca/BigAlsCA/...ripwlunarlight
